Question

Which would be an adaptation for living in the tundra?

funnel shaped leaves to help water runoff
deep roots to go into the permafrost
hibernation to lower metabolism in the winter
large ears to release heat

Answer 1

Hibernation to lower metabolism in the winter.

Reason: tundra is extremely cold with long winters and scarce food, so hibernation helps animals conserve energy. The other choices are unsuitable: permafrost prevents deep roots (plants have shallow roots), large ears lose heat (bad in cold), and funnel-shaped leaves are more an adaptation to heavy rainfall or directing water, not tundra.
